6 Claims.

My inventiongrelates totrimmingboards and, v

more in particular, to a trimming. board. having an improved paper, stop. of theA general,` type shown A,in my prior.` Patents rNos..2,185,'985 and 2,327,000.

A- preferred embodiment, of; the, invention is f shown in the accompanying drawing.. wherein- Fig. 1 is a fragmentary perspective View ofV a trimming board'constructed in accordance with the features of, .myinventiong Fig. 2 is a fragmentary enlarged transverse sectional view taken on the line f2--2 vof Fig. 1; and

Fig. 3 isa fragmentary` transverse sectional view taken on the line 3-3 of Fig. 2.

Looking now to the drawings, the trimming boardof my. invention Vutilizes a base I', preferably made of wood` or. the .likef havingfcross pieces II and with the base preferably provided with suitable indicating lines I2 on the face thereof. A plate I3, providing a cutting edge, is secured along one side of the rectangular base by screws I4 and a cutting knife I6 is suitablyI pivoted to the base so as to cooperate with the cutting edge for the purpose of trimming photographs or the like, with the sides straight and square to each other. i

' In accordance with the general features of my invention, I provide a paper guide I'I along one side of the rectangular base I0 against which the paper may be held in cutting operation and provide a paper stop I8 positioned to gauge the depth of the cut. I provide a pair of ledges at opposite sides of the base with a clamping mechanism so constructed and arranged that the paper stop I8, and a part of the clamping mechanism associated therewith, are tensioned between the two ledges and the paper stop forced tightly against the upper surface of the rectangular base.

In the specific form of invention shown, the paper guide I'I has a general Z shape and a portion thereof I'I' extends downwardly at a slight angle. The lower portion of the Z comprising the paper guide I1 is set in a slightly recessed portion of the top face of the base member and is held in position by screws I9. The opposite edge of the rectangular base I 0 is tapered, as indicated at 2 I, and a hook-like portion 22, which preferably may comprise a part of the paper stop I8, hooks under the ledge comprising the portion 2 I. The clamping mechanism comprises a clamp spring 23 secured to an intermediatel portion of the stop I8 by suitable means such as screws 24, the clamp spring extending toward the opposite end offthe paper stop. and upwardly atan angle andghayinga hook-like. portion .26,l engagingy under-1v the Vledge IIf. A pair of` ears 21; integral with the clamp spring 23, projectupf.- wardly and a clamp 28 Yhas .ears.29 disposed within the ears 2'I",Fa.pin 3I. extending between the two sets of ears to hinge theclamp spring E3 and clamp l28 together. The c1amp;282has.a tail :piece 32 engaging in an opening 33 `in the manner shown-particularly inFg. 2.

When using the-.trimming board, the clampis raised to the,po'siticn Ashown in dotted linesk in Fig. 2 and the paper stop I8 is readily movedto a desiredfposition,y with .respect -tothe cutting edge. The paper 1 stop :andVl clamping. mechanism can be entirelylv removedifrom thel board by merely slidingit beyond'one endfthereof. When the stop has Vbeen placed-at the desired position, however, the clamp is lowered to the position shown in full lines. The paper stop is forced down tightly against the top surface of the base It) by the tail piece 32 and, at the same time, the hook-like portion 26 is forced slightly upwardly and this causes the paper guide to move slightly to the right, looking at Fig. 2. The mechanism is thereby drawn tightly between the two ledges. This drawing action not only results from a virtual shortening of the two end supports but also a clamping action due to the raising of the portion 25 along the slanting edge of the ledge I1.

I have described my invention in detail but the scope thereof is defined in the appended claims.

What I claim as new and desire to protect by Letters Patent of the United States is:

1. In a trimming board, a rectangular base having a cutting edge along one side thereof, means providing a pair of parallel ledges at right angles to said cutting edge, a paper stop disposed parallel to said cutting edge, and means including a pivoted clamp mechanism between ends of the said paper stop for tensioning said paper stop between said ledges and holding it tightly against said base.

2. In a trimming board, a rectangular base having a cutting edge along one side thereof, a paper guide having a ledge along one side of said base at right angles to said cutting edge, means providing a ledge at a side opposite to said paper guide, a paper stop disposed parallel to said cutting edge, and means including a pivoted clamp mechanism between ends of the said paper stop for tensioning said paper stop between said ledges and holding it tightly against said base.

3. ln a trimming board, a rectangular base having a cutting edge along one side thereof, a paper guide along a side contiguous to said edge, said paper guide shaped to form a ledge, means providing a ledge at that side of the base opposite to said paper guide, a paper stop having a hook portion engaging said second ledge, a clamping member having a hook portion engaging said rst ledge, and means including said clamping member and a second clamping member pivoted to the rst mentioned clamping member to draw said hook portions together and fix the position of the paper stop on said base.

4. In a trimming board, a rectangular base having a cutting edge along one side thereof, a paper guide along a side contiguous to said edge, said paper guide shaped to form a ledge,'means providing a ledge at that side of the base Opposite to said paper guide, a paper stop having a hook portion engaging said second ledge, a clamping member having a hook portion engaging said rst ledge, a clamp spring having one end secured to an intermediate portion of the paper stop, said clamping member having a tail piece extending into an aperture in said clamp spring and a pivot connection between said clamping member and clamp spring, so constructed and arranged that said tail piece con nection to said clamp spring when said clamping member is rotated to clamping position will cause shortening of the distance between said hook portions and fix the position of said paper stop on said base.

5. In a trimming board a rectangular base having a cutting edge along one side thereof, a paper guide along one side perpendicular to said cutting edge, said paper guide being of general Z shape and having an upstanding portion delining a ledge running perpendicular to said cutting edge, said base having its opposite side shaped to provide a ledge below its top surface, a paper stop having a downwardly extending hook portion engaging said second ledge. a clamp spring having one end secured to an interrnediate portion of said paper stop and extending slightly upwardly at an angle -beneath said paper guide, and a clamp pivoted to said clamp spring and having a tail piece extending through an aperture therein, said clamp and clamp spring arrangement being so constructed, and arranged that said clamp simultaneously depresses said paper stop against said base and raises the said clamp spring against the ledge to thereby hold the said stop in position.

6. In a trimming board, a rectangular base having a cutting edge along one side thereof, means providing a pair of parallel ledges at right angles to said cutting edge, a paper stop having a hook-like portion engaging under one such ledge, a clamp member having a hook-like portion engaging under the other such ledge, and a pivoted clamp between said paper stop and clamp member to force the paper stop against the base and tension said hook-like portion between the said parallel ledges.
